To all whom it may concern:

Be it known that we, ANTON M. SGHEURLE and Josnrrr M. STINE, of Kiel andMilwaukee, Wisconsin, respectively, have invented Vulcanizing-Mold, forRubber Tires, of

which the following is a specification.

This invention relates to devices for repairing rubber-tires by thevulcanizing process, and more particularly to that type of 1a deviceswhich comprises a mold-box having a chamber or recess to receive. thetire or a portion thereof and a separate and adjacent chamber for steamor other fluid for heating the box to the requisite temperature requiredfor vulcanizing. Such vulcanizingmolds ordinarily are provided withclamps for holding the tire which is being vulcanized in contact withthe recess provided.

for it and pressing it against the walls thereof. Such clamps as atpresent constructed are separate from the box so that when the tire isbeing removed they fall away from the box,- and moreover they so embracethe box as to interfere with the steam-pipe supplying the same incertain positions.

The object of our invention is toimprove this type of apparatus byproviding a simple portable form of mold-box with a readily. attachableand detachable clamp which can be placed. at any point of the boxdesired and can be quickly adjusted in position and raised while itremains attached to the box in the proper position; and to provide aconnection whereby any number of said clamps may be attached to the boxinthe desired positions.

According to our invention we provide on one side of the box alongitudinal dove. tailed rib, and we provide each clamp with abase-member having a dovetailed recess adapted to engage with andslideupon said rib whereby it is prevented from becoming detached unless .itis slid ofl the end of said rib, and on the other side of the box weprovide 'a longitudinal lug which is adapted to be engaged at any pointby a hooked catch-piece forming another member of said clamp.

-The nature of our-invention will best be i understood by aconsideration of the following detailed description, reference being hadto the accompanying drawings, in Which Figure 1 is a side view ofa'complete apparatus, the left-hand end being shown in longitudinalsection; Fig-2 is a fragmentary side-view of the central-portlon and"one clamp, from the opposite sidefrom Fig. 1; and Fig. 3 is alongitudinal central-sec-v tion through the mold-box showing a clamp inoperative position thereon, partly in section and partly in elevation.

The reference letters refer each to the same part in each figure of thedrawings.

The mold-box A is of arcuate shape conforming in radius of curvature asnearly as possible to the size of the tires for which it is to be used;said box has in its upper side a recess a conforming in cross-section tothat of the tires, and immediately below the same, a closed chamber afor steam or other heating fluid, which is admitted thereto by means ofa pipe B screwed into an aperture a Pet-cocks 00' may be provided at theends to let out cold air in order to heat said chamber quicker. On oneside of said moldbox is formed a dovetail-shaped longitudi-.

nal rib or lug a, and on the opposite-side a second longitudinal. rib orlug a, whose lower face is slightly undercut or recessed as shown. 1

Each joint-clamp comprises three principal members, to wit:-abase-member C,-a

yoke D and a hooked catch-piece E, said members being pivoted togetherby pins F and G. The base member C has an undercut recess 0 which is ofthe same shape as the lug a and is adapted to slide over the latter asshown; whereby the clamp may be placed in any position along the lengthof the mold-boxand when so placed will re main there without fallingaway from the box. To prevent longitudinal displacement, a set-screw H,threaded into the member C and pressing against the lug a may be used,though this is not necessary. The member D is adapted to span the upperopen side of the mold-box and has a screwthreaded recess 03 in whichworks a screwstem 1, and said screw-stem has mounted in a swiveledmanner upon its lower end a circular flanged disk or .other likepressurepiece 2', which is adapted to press upon the pressure-pad J,which fits inside the tire, and the ofiice of which is to press' thelatter against the lower surface of the recess a. The swivel-plate 2"may be held in place by a screw 2' On the upper end of the stem I islocated means for rotating the same; said means comprising as shown thesquared end i for a wrench, and below the same, a handwheel M secured onthe stem by a dowel m or otherwise. On the member I) is formed a lug (Z2to support it when raised and pre vent it from falling over. Thecatch-piece E is provided with a hooked engagingsurface 6 which isarranged to engage the lower undercut surface of the lug a, as shown inthe drawings, whereby said yoke is held in its transverse position whenthe screw-stem I is rotated to press the tire T into its recess asabovedescribed.

It will be seen that any number of clamps may be used side by side, orat as frequent intervals along the tire as may be found desirablewithout interfering with each other; and may be set or removed with aminimum of efiort and manipulation.

We wish it understood that our.invention is not limited to the use ofall the above described features and constructions, for

some may be omitted and others may be varied or modified in variousways, as will readily occur to those skilled in the art.

Having thus described our invention, what we claim as new and desire tosecureby LettersPatent, is:

1. In combination, a vulcanizing moldbox and a clamp therefor, saidmold-box having a recess in one side adapted to re ceive a tire, andsaid clamp comprising three elements pivoted together, to wit :-abasemember at one end, a yoke-member in the middle and a catch-member atthe other end,

and means on said yoke-member for pressing the tire into said recess;said box being provided on each side with a longitudinally extendingengaging-surface, said base-memher having a-coacting face adapted to emgage in a longitudinally slidable manner with one of said engagingsurfaces, and said catch-member being provided with a coacting-surfaceadapted to engage with said engaging-surface on the other side of saidbox.

' 2. In combination, a vulcanizing moldbox for tires having alongitudinal recess surfaces of the box, whereby said clamp can be movedto any position longitudinally of said box and can be removed therefromonly by sliding it off the end thereof.

3. In combination, a vulcanizing moldbox having in its upper face alongitudinal recess adapted to receive a tire and a yoke-shaped clampadapted to bridge said recess; said mold-box having on each side alongitudinally running undercut surface and said clamp having on eachend an undercutsurface adapted to engage in a slidable manner ,with therespective undercut surface of said box; whereby said clamp remainsattached to saidbox unless slid endwise off the end thereof.

4.. In combination, a vulcanizin moldbox having in its upper face alongitudinal recess adapted to receive a tire and a yokeshaped clampadapted to bridge said recess; said box having on each side alongitudinally running lug having an undercut surface and said clamphaving on each end a member with a hooked-surface adapted to engage in aslidable manner with the under surface of said lug; whereby said clampremains attached to said box except as it may be slid endwise offthe endthereof.

5. In combination, a vulcanizing moldbox having its upper face alongitudinal recess adapted to receive a tire and a yokeshaped clampadapted to bridge said recess; said box having on one side a dovetailedlug and saidclamp having on one end a dovetailed recess, conforming tothe crosssection of said lug whereby it may be engaged therewith only bysliding it over the end thereof and maybe moved to any position alongthe length of said box.

I 6. In combination, a vulcanizing moldbox having in its upper face alongitudinal recess adapted to receive a tire and a yokeshaped clampadapted to bridge said recess; said box having on one side a doveend adovetailed recess'eonforming to the cross-section of said lug whereby itmay be engaged therewith only by sliding it over the end thereof andmay-be moved to any position along the length fjsaid box; said .boxhaving on the opposite side a lug having an undercut lower surface andsaid clamp having 'a member with an undercut surface adaptedto engagewith the undercut surface of said last-named lug.

7 In combination, a vulcanizing-box having a longitudinal recess adaptedto receive a tire, and on one side thereof a longitudinal dovetailedlug, a clamp comprising a basemember having a recess adapted to engagein a slidable manner with said lug, a yoke pivotally connected to saidbase-member, and means for securing the free end of said yoke to theother side of said box.
